In Wario Land II, Wario could not be defeated by any enemy. Instead, some of the foes triggered transformations. Tiny Wario was among these alterations. The status effect can only be caused by a Wizard. With a shake of its wand, the Wizard turns Wario tiny. In this state, Wario cannot attack any enemies, but he is able to leap higher. The physical condition could be reversed if Wario falls into water or gets hit by an enemy. Also, the Wario Land II transformation is similar to the eventual Mini Mario form introduced in New Super Mario Bros.

In WarioWare: Smooth Moves, Wario receives a small, pink motorbike from Penny that shrinks him and separates him into multiple Tiny Warios. It is the final stage of the game.

In Wario Land: Shake It!, a form of Wario called Mini Wario appears but unlike Tiny Wario it is just a smaller version of normal Wario with no physical changes whatsoever.

In Game & Wario, robotic MechaWario minions resembling Tiny Wario are the main enemies in the minigame "Arrow".

Tiny Warios (in their Smooth Moves design) makes an appearance in the Rhythmware challenge set of Rhythm Tengoku: The Best+. The set's version of Freeze Frame features Tiny Warios as the racers Dr. Crygor must take photos of, replacing the regular race cars from the original version.
